JOSEF SCHULZ, 0F BUDAPEST, AUSTRIA-HUNGARY.

BOAT ANI) OAR T'HEREFOR.

To all whom t may concern.'

Be it known that I, JOSEF SCHULZ, a subject of the Austro-Hungarian Emperor, and resident of Budapest, Austria-Hungary, in the Austro-Hungarian Empire, have invented Improvements in Boats and 4Oars Therefor, of which the following is a specification.

This invention relates to boats and oars therefor and has for its object a device which enables the oarsman to row with his face in the direction of the course to be taken.

In the drawing zFigure l shows a plan of part of a boat with the device applied; Fig. 2 shows a plan, partly in section and on a larger scale, of said device; Fig. 3 shows a section through line A-B in Fig. 2, and Fig. 4 shows a detail.

In carrying out my invention I mount on the upper face of the side walls a of the boat a support comprising two bearings b each of these bearings serving to receive a shaft c lying parallel with the longitudinal center line of the boat. The two shafts form the integral projections of a disk Z the center thereof being penetrated by a bolt e which constitutes the means for connecting a casing f, carried by the shafts c, and its cover g, Fig. 3. Above and below the disk d and rotatably mounted on the bolt e are conical and toothed wheels h and z' respectively, the wheel L being provided with an integral and cylindrical sleeve Z and the wheel t' being similarly formed with a sleeve m. These sleeves are split in the manner shown in Fig. 2 and adapted to receive respectively the end of the handle o of the oar and the end n of the oar proper. Two conical and toothed wheels p are moreover arranged one each on the vshafts c and within the casing f in such a manner, that they engage with the aforedescribed wheels 7L and z'. Upon the pulling of the handle 0 in the direction of the arrow, Fig. l, the wheel c' is rotated such rotary movement being consequently transmitted to the wheels p and the wheel h, the latter in turn causring a movement of the oar in the direction of the arrows, Fig. 1. Both the upper and lower wheels 7b and z'` are preferably bearing on rollers to insure smooth working.

If desired, the piston rod of an air pump r may be linked to the sleeve m, as illus- Specification of Letters Patent.

Serial No. 792,116.

trated in dotted lines in Fig. 1, the said pum being suitably attached to the side of the oat and the purpose thereof being to allow of training when the boat is out of use and when the oars have been detached.

Having now fully described my said invention what I claim and desire to secure by Letters Patent is l. In the hereindescribed device for boats, the combination with two bearings in the forni of a support mounted on the side wall of the boat, of a horizontally disposed disk having oppositely arranged projections in the shape of shafts which `are journaled in said bearings, a casing and cover mounted between the vbearings and on the shafts, a bolt connecting the cover and bearing, a conical wheel carried by the said bolt both above and below the disk, the said wheels having integral extensions in the form of split sleeves of which one serves to receive the oar and the other a handle, and intermediate gearing to transmit motion from the wheel and sleeve bearing the said handle to the wheel and sleeve carrying the oar, substantially as specied and shown.

2. In the hereindescribed device for boats. the combination with two bearings in the form of a support mounted on the side wall of the boat, of a horizontally disposed disk having oppositely arranged projections in the shape of shafts which are journaled in said bearings, a casing and cover mounted `between the bearings and on the shafts, a

bolt connecting the cover and bearing, a conical wheel carried by the said bolt both above and below the disk, the said wheels having integral extensions in the form of split sleeves of which one serves to receive the oar `and the other a handle, intermediate gear- `to connect the piston rod of said pump with the oar, all as described and shown.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
